WooCommerce to Sellsy
Orders → invoices
Turn eligible WooCommerce orders into Sellsy invoices while reusing the billing customer, order lines, quantities, prices, shipping, taxes, coupons and payment references already produced by the store.
WooCommerce sales, ready for the Sellsy back office
WooCommerce + Sellsy integration
Move the ecommerce sale from WooCommerce into Sellsy without asking finance to reconstruct it. Synchron can turn eligible store orders into Sellsy invoices, match or create the customer, carry across the commercial detail behind the checkout, and let your finance team decide how far invoice validation and payment automation should go.
- Turn eligible WooCommerce orders into Sellsy invoices
- Carry customer, shipping, tax, coupon and payment context forward
- Keep invoice validation and payment automation under finance control
Keep the storefront flexible and the back office structured
Turn the WooCommerce order your store already understands into the Sellsy invoice finance needs
WooCommerce gives merchants a highly flexible way to sell, which also means the financial meaning of an order can depend on store-specific statuses, tax rules, shipping methods, coupons and payment behaviour. Synchron carries that completed ecommerce context into Sellsy so the back office can work from a structured invoice and customer record instead of rebuilding the transaction from separate pieces.
Use your ecommerce lifecycle as the billing trigger, preserve the commercial detail behind the sale and keep finance in control of the final document
Connected workflows
Connect the WooCommerce sale to the Sellsy invoice process
This integration focuses on one important hand-off and does it thoroughly: turning the right WooCommerce order into a Sellsy financial record with the customer and transaction context needed by the back office.
How it works
From a WooCommerce order state to a Sellsy invoice your finance team can use
The hand-off starts with the ecommerce lifecycle your business already trusts and carries the order into Sellsy without stripping away the commercial context behind it.
- Step 1
WooCommerce determines when the sale is ready
The integration can focus on the order statuses that represent the point at which your business considers a sale ready for invoicing.
- Step 2
The customer is matched in Sellsy
Billing information from the order can be used to find the existing Sellsy customer or create the customer context needed for the invoice.
- Step 3
The ecommerce detail becomes the invoice
Products, quantities, pricing, shipping, taxes, coupon context and payment references can travel with the order instead of being re-entered by finance.
- Step 4
Sellsy takes over the downstream process
Once the invoice exists, validation, payment recording and related Sellsy document handling can follow the level of automation your finance operation is ready to use.
Operational visibility
Keep the order-to-invoice hand-off visible
Because this integration creates financial documents, a missed order or incorrect hand-off deserves a clear operational trail. Synchron makes the transfer observable so teams can see whether the WooCommerce sale reached Sellsy and investigate the source context when it did not.
-
Follow the store order into Sellsy
Keep the connection between the originating WooCommerce order and the Sellsy invoice process visible as finance takes over.
-
Use controlled manual imports when needed
Test a known order, backfill historical sales or reprocess a corrected case without changing the business rules that govern the normal automated flow.
-
Investigate exceptions from the commercial source
When customer, status, tax or order data prevents the expected result, your team can review the affected transaction in context before trying again.
Why Synchron.io
Connect a flexible WooCommerce storefront to a disciplined Sellsy finance process
WooCommerce can be customised around the way a merchant sells. Sellsy is where the resulting customer and invoice records need consistency. Synchron bridges those two priorities without forcing either team to abandon the system built for its work.
Remove repetitive invoice entry
Reuse the order data already captured online instead of asking finance to copy customer, product, shipping, tax and payment information into Sellsy.
Respect the store lifecycle
Start invoicing from the WooCommerce order states that represent a real billing event for your operation.
Preserve finance controls
Automate document creation without assuming invoice validation or payment recording should happen before your team is ready.
Keep customer records connected
Use checkout identity and address information to support the Sellsy customer record behind each ecommerce invoice.
Keep the financial hand-off observable
Give teams a visible integration trail for the WooCommerce orders that become Sellsy invoices and the cases that require review.
Use the WooCommerce order lifecycle as the gate to invoicing
A WooCommerce order can move through several operational states before finance should act. Synchron lets the invoicing hand-off begin from the point that makes sense for your store rather than assuming every new order is immediately ready for the books.
Invoice from the states your operation trusts
Choose the WooCommerce lifecycle points that mean the customer order has reached the level of certainty your finance team expects before a Sellsy invoice is created.
Avoid premature financial documents
Keep orders that are still moving through an earlier operational stage out of Sellsy until they meet the business rule used for invoicing.
Keep the trigger aligned with store customisation
If your WooCommerce operation uses its own status conventions or extensions, the invoicing model can be planned around the lifecycle your team already follows.
Carry the commercial detail behind the WooCommerce checkout into Sellsy
An invoice is more than an order total. Shipping, discounts, taxes and payment references all influence how finance understands the transaction. Synchron reuses that ecommerce context so Sellsy receives a document built from the sale that actually happened.
Preserve the product and quantity story
Use the order lines and product references from WooCommerce as the basis for the Sellsy invoice instead of rebuilding the basket manually.
Keep shipping and coupons visible
Carry the delivery charges and discount context that changed what the customer paid so the back-office document reflects more than just the merchandise.
Respect tax and total behaviour
The integration can be configured around how your WooCommerce store represents tax and totals so finance can review Sellsy documents against the commercial source.
Retain payment references
Where payment information matters to reconciliation or follow-up, the Sellsy record can stay connected to the payment context captured by WooCommerce.
Let finance decide when invoice automation becomes final
Creating the Sellsy invoice and finalising it are separate decisions. Synchron can start by removing data entry while leaving finance with a review checkpoint, then support deeper automation once the output has been validated against your process.
Begin with review-first invoicing
Create the Sellsy document without forcing immediate validation so the finance team can inspect early imports and confirm the mapping is behaving as expected.
Automate validation when confidence is high
Once the process is stable, invoice validation can become part of the automated hand-off when that matches your internal controls.
Reflect payment when appropriate
If WooCommerce already contains the payment information finance relies on, the workflow can also create the corresponding Sellsy payment record rather than leaving a paid ecommerce sale looking unpaid in the back office.
Add related Sellsy documents when the process needs them
Where your administrative workflow uses a Sellsy order document alongside the invoice, it can be created as part of the same hand-off instead of requiring another round of manual entry.
Keep the customer identity connected from checkout to back office
Finance should not have to guess which Sellsy customer belongs to a WooCommerce order. The integration can use the billing information captured at checkout to connect the transaction to the appropriate customer record and carry useful delivery context with it.
Match before creating another customer
Use the WooCommerce billing identity to look for the corresponding Sellsy customer before creating a new record for the invoice.
Create the back-office customer when needed
If the customer does not yet exist in Sellsy, the order can provide the information needed to establish the financial record without a separate onboarding step.
Include shipping context when useful
Delivery-address information can be carried into Sellsy when finance, support or logistics teams need that context around the customer.
Keep ecommerce records identifiable
Sellsy records created from WooCommerce can remain easy to recognise and organise for reporting or operational follow-up.
Questions, answered
Shape invoicing around the way your WooCommerce store actually operates
These are the practical questions teams ask when WooCommerce should remain the sales source while Sellsy takes ownership of invoicing and financial follow-up.
Your WooCommerce invoicing process has another rule?
Tell us which store orders should become invoices, how finance reviews them and which customer, payment or document details matter in Sellsy. We can discuss how the hand-off should fit around your existing process.
Can WooCommerce orders create invoices in Sellsy?
Yes. Synchron can turn eligible WooCommerce orders into Sellsy invoices while carrying the customer, order lines, pricing, shipping, tax, coupon and payment context needed by the back office.
Can we choose which WooCommerce orders should be invoiced?
Yes. The order lifecycle can be used to define which WooCommerce statuses represent a sale that is ready to enter the Sellsy invoicing process.
What happens if the customer does not already exist in Sellsy?
The workflow can use WooCommerce billing information to match the appropriate Sellsy customer and can create the customer context required for the invoice when no suitable record exists.
Can Sellsy invoices remain available for review before validation?
Yes. Automatic validation is optional, so teams can begin with review-first invoice creation and introduce further automation after the generated documents have been checked against the finance process.
Can a paid WooCommerce order also create a Sellsy payment record?
Yes. Payment creation can be included when the WooCommerce payment information should be reflected in Sellsy as part of the financial hand-off.
Can the workflow create a Sellsy order document as well as the invoice?
Yes. A related Sellsy order document can be included when your back-office process requires it alongside the invoice.
Does this integration also synchronize WooCommerce refunds or Sellsy stock?
The documented WooCommerce + Sellsy workflow currently focuses on importing WooCommerce orders into Sellsy invoices. Refund, credit-note and inventory synchronization should not be assumed for this pair unless they are added and confirmed separately.
How do we monitor the WooCommerce + Sellsy integration?
Synchron keeps the order-to-invoice hand-off observable so your team can review which WooCommerce sales reached Sellsy, investigate exceptions and use controlled manual imports for testing, backfills or corrected cases.
